Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.
An ultra low temperature (ULT) freezer is a refrigerator that stores contents at −80 to −86 °C (−112 to −123 °F). [1] An ultra low temperature freezer is commonly referred to as a "minus 80 freezer" or a "negative 80 freezer", referring to the most common temperature standard. [2] ULT freezers come in upright and chest freezer formats.
